Clinical notes

Hanyan is a key local point for treating temporal headaches and migraines, especially when the pain radiates towards the eye. Its location at the temporalis muscle makes it effective for conditions involving the jaw, such as bruxism, TMJ disorders, and trismus. As a meeting point of three yang channels on the head, it is well-suited to clear wind and heat causing dizziness, tinnitus, and eye pain.
